Overview
The DRV8231ADDAR is a Texas Instruments integrated H-bridge motor driver designed for brushed DC motors. It operates within a supply voltage range of 4.5 V to 33 V and delivers a peak output current capability of 3.7 A. The device features an internal N-channel MOSFET configuration with a typical on-resistance (RDS(on)) of 600 mΩ. It utilizes an IPROPI pin for integrated current sensing, eliminating the need for external shunt resistors. The component supports PWM control interfaces compatible with 1.8 V, 3.3 V, and 5 V logic levels and includes protection mechanisms such as UVLO, OCP, and thermal shutdown.
Feature Summary
- Integrated N-channel H-bridge architecture with charge pump for high-side gate drive
- Built-in current mirror sensing via IPROPI pin for stall detection and regulation
- Low-power sleep mode achieving ultra-low quiescent current consumption
- Comprehensive protection suite including under-voltage lockout and over-current protection
Applications
- Industrial automation systems requiring precise motor control
- Medical equipment utilizing small form-factor actuators
- Consumer appliances with brushed DC motor drives
- Battery-powered devices necessitating low standby power consumption
Procurement Notes
Verify the specific suffix 'DDAR' against the manufacturer's official datasheet to confirm the package type and tape-and-reel specifications. Ensure compatibility with system voltage rails and logic levels before integration. Confirm RoHS compliance status through the latest documentation provided by Texas Instruments.
Selection Notes
Select this component when designing circuits requiring integrated current sensing without external shunt resistors. It is suitable for applications demanding a compact footprint and low static current in sleep modes. Consider the 33 V maximum rating and 3.7 A peak current limits relative to the target motor load requirements.
Part Context
This part belongs to the DRV8231A series of H-bridge drivers from Texas Instruments. The family offers scalable options with varying RDS(on) and voltage ratings. The DRV8231ADDAR specifically denotes the WSON or HSOP package variant equipped with the integrated current mirror feature set.
Replacement Considerations
The DRV8231A serves as the base model for this component. Other variants within the DRV8231 family may offer different on-resistance values or voltage ranges while maintaining pin-to-pin compatibility.
